FGC UES to Improve Signal Lighting in Western Siberia

UrBC, Moscow, October 5, 2017. Rosset’s Federal Grid Company United Energy Systems is going to renovate the signal lighting appliances in places where electric main support beams intercross with large rivers in Western Siberia, the company press service reports.

The crossings will be fitted with 129 new lights and 482 batteries. The new equipment is meant to ensure extra safety for airplane pilots at nighttime and in poor visibility conditions.

According to the electric main operation and maintenance requirements, support beams that are over fifty meters tall must bear special marking and be fitted with signal lights. The red lights must be installed in the upper part of the beam and then at every forty-five meters down to the level where they can’t present any danger for airplanes or helicopters. For example, a 90-meter-tall beam needs two tiers of signal lights, a 188-meter-tall one will need four tiers.

33 signal lights and 68 batteries have been replaced so far at crossings on Irtysh, Tobol, and Ob. Also, solar battery-operated protective appliances got installed at support beams of Surgutskaya Power Station 1-Pyt-Yakh 500-kilowatt electric main.
